“For current KPMcore, the boot and esp flags are the same thing, so this is not a Calamares decision. And KPMcore also only changed it because libparted did. I guess it could be changed back now that KPMcore uses sfdisk instead of libparted, but it is an upstream KPMcore issue and any change there is an API and ABI change for KPMcore.”
Yes I use a rather unorthodox partitioning scheme.
If you chrooted and installed the bootloader successfully for UEFI system, I don’t know why your bios doesn’t find the path to booloader. If the bootloader did install correctly, it is possible to create a bios efi boot manually from the live usb. I don’t know if it will work but if you want to try:
I start thinking maybe something is “wrong” with your bios. I cannot think of anything else right now. You can check perhaps if there is a bios update for your machine.
Something I came to think of is that you might be able to do a Legacy installation. You could disable UEFI in the bios and then install in Legacy. The disk should be msdos instead of GPT. The bootloader goes into the MBR of the drive. No need for EFI partition.
